Question

Problem page the length of a rectangle is six times its width. if the perimeter of the rectangle is 98 cm , find its area.

Answer 1

Let width be x. 

Length: 6x 

P=2(l+w) 
98=2(6x+x)
98/2=7x 
49=7x 
49/7=x 
7=x 

Therefore, the width is 7 and the length is 7*6=42 

Area=lw
A=(42)(7)
A=294 cm²

Hope I helped :)
